Research and Development

Research and development at the Chair for Network and Data Security concentrates on cryptographic protocols, Internet security and XML security. Our goal is to propose new solutions based on a thorough knowledge of techniques and standards in these areas.

Cryptographic Protocols

Cryptographic protocols form the basis of many security solutions, from well-known Internet standards like SSL to little-known broadcast encryption techniques für blue ray disks. We try to prove the security of these protocols in a model that is as close as possible to reality. An especially challengig area is group based cryptography, becasue here we have to model concurrency, participation in different groups, and malicious group members.
